About Soul Points, I currenly have Arthur and Siegfried, I've leveled both Roland and Cassiopea and I'm currently attempting to get Andromeda for the Yata Garasu event since I don't like the Glasscannony-esque vibe my team gives, as leveling my rank after the high 40's it's been difficult to level up, to get Soul points, even on Sunday EXP day

Question is, since I just have 3 weeks in the game; when an event boss such as Yata comes, is there any easier way than leveling for Soul Points to get it?

Defeating the raid counts as easier since I'm prepared with a 70+ Water Team
